Subject: [PATCH] Only consider chunks Loaded if at BORDER status
|
||||
|
||||
This greatly improves performance as it drastically reduces the amount
|
||||
of Entities and Tile Entities that are "registered" into the world, as
|
||||
purely "cached" chunks will no longer have their entities hanging out in the world.
|
||||
|
||||
Additionally this fixes our Entity Add To World and Entity Remove From World events
|
||||
|
||||
Those events have not been firing correctly since MC changed how chunks work here.
|
||||
|
||||
Now the server will only consider a chunk "loaded" if it's got a ticket putting
|
||||
it at level 33 or lower, which matches the public Bukkit API.
